BACKGROUND OF THE INVENTION 1. Field of Invention The field of the invention lies in the art of concrete forming wherein forms are disposed to receive poured concrete to form a concrete wall.

2. Description of the Prior Art The prior art is replete with forming frameworks and concrete molds which generally consist of large wooden or steel panels placed in a rectangular like configuration and provide a mold into which the concrete is poured. Such panels may be of different sizes and are generally interconnected in a removable manner so that they can be carried from job site to job site. Even though the prior art panels are made of smaller sizes, they are nevertheless unsuitable to provide a fine finished concrete wall of a type which is desired in better building construction. Large steel molds which are used for large building construction and which provide a good outer surface are cumbersome, hard to handle, require many men and cranes and cannot be readily moved from job site to job site. Smaller panels which are easier to handle require many cross ties to secure them together. Usually such molds require several cross ties at everyside joint where the panel is connected to an adjacent panel. The cross ties are difficult to assemble and require much time. More importantly, however, they permit water to seep therethrough during concrete pouring and thereby leave linear projections in the completed wall that clearly show the parting lines of the mold and provide an unsightly construction. Thus, the larger molds and smaller molds both have disadvantages which are solved' by the construction disclosed in the present invention. Further, the flat panels which are removably interconnected, in the prior art, are reused numerous times and due to wear, etc., they frequently produce a very rough outside surface finish on the concrete walls after the panels have been stripped therefrom. Thus, while some of the advances in the prior art have been a reduction in the size of the panels, permitting them to be more easily assembled into a mold structure, the problem still remains in that they are reused, and leave a very undesirable face for this reason as well as that which is stated above.

SUMMARY OF THE INVENTION It is a prime object of the present invention to provide an improved concrete form wherein panels which are used to form the mold into which concrete is poured are disposable and/or which remain in place and are integrally formed with the concrete to provide a wall structure including an insulating sheet and a sheet bonded thereto which forms a finished wall of the concrete wall structure. Further, the form includes a framework which is quickly assembled and disassembled on site and consists ofa minimum of parts of lightweight construction such as for instance, aluminum or other strong lightweight material. The framework is constructed in a manner providing great strength and rigidity for supporting the panels and includes interconnecting members light in weight and being readily constructed in assembled form by a single worker and effectively and cleanly form large surfaces without the disadvantages of the present large metal molds used in large building construction. Since the panels, which form the mold, are disposable and/or form part of the' wall structure, and since the framework details may be readily reused from job to job a smooth and attractive concrete wall structure results in each instance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 2 is an end elevational view of the wall form and framework of FIG. 1;

FIG. 3 is an enlarged cross-sectional view taken substantially along the line 33 of FIG. 1;

FIG. 4 is a cross-sectional view taken substantially alongthe line 44 of FIG. 2 with a scaffold removed; and

FIG. 5 is a detailed sectional view taken substantially along the line 55 of FIG. 4.

FIG. 6 is a schematic view in partial cross-section of modified wall construction and different use of concrete form.

Referring to the drawings, a concrete wall form is designated at 10 and includes a pair of laterally spaced substantially parallel horizontally extending H-shaped base members 1 1. Each base member comprises a horizontal web 12 and includes upper legs 13 and lower legs 14. Each of the base members 11 is adapted to support a plurality of upright members 15 which are carried on said base members 11 in' longitudinally spaced relation along said base members. Each of the upright members 15 includes the web 16 which extends substantially normal to and in T-shaped relation with respect to flat plates 17. The webs 16 as best shown in FIG. 2 are relatively wide at their lower ends, converge upwardly and are relatively narrow at their upper ends.

As best shown in FIG. 3, the lower ends of the webs 16 are provided with laterally spaced vertical slots 18 to provide at said lower ends a projecting tongue designated at 19. The tongues 19 are seated within a space on each base member 11 provided between the upper legs 13 and thus are held in position against lateral displacement. As best shown in FIG. 2, the lower portions of the webs 16 of each upright member 15 are provided with a plurality of vertically spaced large openings 20, the said openings 20 of each of the upright members 15 being in horizontal alignment when placed in position on a base member as shown in the Figures. Immediately above the uppermost of the larger openings 20 in each web 16, a plurality of smaller holes or openings 21 are provided. Longitudinally extending tubular members 22 are carried in the larger openings 20 and extend therethrough as best shown in FIGS. 1 and 4. The tubular members include at horizontally spaced portions thereof vertical aligned slots 23 in which wedges 24 are adapted to be inserted. As best shown in FIG. I, the wedges 24 are driven in place against the webs [6 to tightly and'removably connect the tubular members 22 in position within said webs. To further retain the upright members 15 in position and to support the same so that the plates 17 of each series of upright members remain in the same vertical plane horizontal rods 25 are provided withinthe smaller openings 21.

As best shown in FIGS. 1 and 3, transversely extending tie rods 26 are provided at longitudinally spaced points along each base member 11. The tie rods 26 extend through openings 27 provided in the upper legs 13 and each tie rod further includes openings 28 for receiving wedges 29 which are driven therethrough to secure the base members 11 against outward transverse movement during the pouring of concrete. The upright members 15 are also secured against upper transverse movement by means of tie rods suitably supported on the tubular members 22 and horizontally spaced points as best shown in FIG. 1. The tie rods 30 are provided with openings 31 through which wedges 32 are driven. The tie rods also extend through openings or slots 31 in the tubular members 22 as best shown in FIG. 4. The upright members 15 are further supported against relative transverse upper movement by means of channel shaped brackets 33 each being interconnected by a suitable bail member 34.

As best shown in FIG. 4, the mold is formed on one side with a disposable panel 35. The panel or lamina 35 may be of Masonite construction or may be of any suitable fiber or paper board which is expendable after each concrete pouring. The panel 35 has in its inner surface a suitable pattern (not shown) which may leave any desired design such as a brick configuration, etc. on the finished concrete wall outer surface. Even though the panel 35 may be of relatively light construction as indicated, the placement of the vertical or upright members 15 is such that it is sufficiently reenforced for forces encountered during the pouring of concrete. Further, the mold is formed by a dry wall panel or lamina 36 which in the finished condition of the wall forms an inner finished wall surface of the par ticular room or building which is so constructed. An insulating panel or lamina 37 may be suitably bonded to the inner surface of the dry wall panel 36 and thus this combination forms another wall of the mold into which the concrete is poured. The insulating panel 37 may be of a suitable plastic of expanded polymeric materials which are well known in the art. As best shown in FIG. 4, an end of the mold may be provided by a dry wall panel 36 extending transversely. While FIG. 4 shows the corner design and use of the improved concrete wall form, the end of the mold may be suitably formed also with another dry wall panel 38 as shown in the left hand view of FIG. 4 to provide a rectangular mold construction. Thus, the construction disclosed in FIG. 4 is representative of the manner in which both ends of the mold may be formed.

The panel 38 is suitably held in position by means of a pair of upright members 15 with their walls suitably provided with large openings 20 as hereinbefore described. A short tubular section 39 is placed through the openings 20 and a right angle tubular connector 40 is provided to connect the section 39 .to the adjacent longitudinal member 22. A hole or opening 41 is provided in the elbow type of tubular connector 40. The short section 39 is provided with slots or aligned openings 42 and wedges 43 are driven through the holes 41 and 42 for tightly but removably connecting the tubular elbow 40, short tubular section 39 and the longitudinal tubular members 22. Such a connecting arrangement is provided for each of the tubular members 22 shown in FIG. 2 thereby rigidly supporting the panel 38 of the mold. FIG. 4 also shows the arrangement of the elbows at a corner wherein the elbows are connected to the long length tubular members 22 for assembling the framework to construct a corner.

THE OPERATION As indicated hercinabove, the prime advantages of the present construction is that all of the parts are of light weight construction and provides the advantage of large mold forms. Therefore, the parts are made of aluminum or similar material having great strength and yet being light in weight. Also, the parts can readily be assembled and disassembled and moved from site to site in that it is not required to have heavy panel type forms which are difficult to transport and difficult to assemble when the site is reached. Such construction usually requires many men and cranes for hoisting and handling the large members. In a present instance, the mold is formed of panels which become integral with the concrete and as in the case of the disposable or expandable panel is merely stripped and discarded after the concrete wall is formed. In building the form, it is a simple matter to place the base members in position and to then place the upright members 15 on the base members while the tubular members 22 are inserted into the openings 20 in which then keep the base members in their relative up-right relation. The upright members 15 may be moved on the base member to an infinite or to any position since they are not secured to the base members against vertical displacement and are primar ily positioned thereon against transverse displacement which. is limited by means of the tie rods 26 placed in the assembled position shown in FIG. 3. Placement of the upright members 15 in position, therefore, is relatively simple in that the wedges 24 are merely driven in place as indicated so that the tubular members 22 are tightly held in position.

The rods 22 also serve to re-enforce the structural strength of the total frame and also to guaranty alignment of the members 15 so that the plates 17 are maintained in the same vertical plane. Also it is a simple matter to insert the tie rods 30 through the openings provided in the tubular members 22 so that they are further retained and in return retain the and upright members against the pressures tending to move them laterally outwardly during the pouring operation. In each instance, it is a simple matter to drive the wedges into position to assemble the members 22, 39 with the upright members 15 to provide a framework of strong and yet lightweight construction. The web 16 of each of the members 15 is wide at the bottom and narrow at the top which again provides for greater strength at the place where it is needed namely at the bottom of the mold and yet the upright members 15 are easy to transport and can readily be handled by a single operator. By the utilization of the present concrete form, a single operator can quickly place the framework and molds into position and knock the same down after the concrete has been poured. Clearly a framework has been provided which is simple, consists of few parts many of which are interchangeable, and which are light and do not require any special tools during the assembly operation. It is obvious that the only tool which may be needed may be a hammer for driving the various wedges in place. It is unnecessary to utilize cranes or other devices for hoisting the members in position since each of the parts can be readily carried by a single man. As best shown in FIG. 1, if it is desired, the longitudinal tubular members 22 may be staggered and may be of shorter or longer length as desired so that the length of the tubular members may be varied and reduced to thus assure greater facility in handling. Also as shown in FIG. 2, it is a simple matter to provide on the framework a removable scaffold 45 which is supported on the rods 25 and members 22.

connectors, and tubular members 22. Elimination in' most instances of the cross ties therefor also provides the desired advantage not disclosed in the prior art. In the present form, a single man can assemble and disassemble the same and yet secure the advantage of the large heavy steel molds of the prior art which also have the disadvantages hereinabove described.

As shown in FIG. 6, the framework may also be expe ditiously used for forming a retaining wall or similar wall which is wide at the bottom and narrow at the top. The base members are merely spread apart on the ground and the upright members are tilted on the base members. The tie rods 26 are usually sufficiently long and contain a sufficient number of openings 28 for the wedges 29 to accommodate thewider lower end of the retaining wall.
